Editors’ fees vary so drastically that authors are often (rightfully) confused about how much to pay. I’ve seen copyediting fees that range from $20/hour to $300/hour. That said, I’ve seen plenty of authors pay $20/hour for a poorly executed copyedit that needed to be redone. I know one author who paid $200/hour for a copyeditor who’d worked on a famous best-seller, operating under the false assumption that a good copyedit would be their ticket to best-seller status. That didn’t happen. Get a few bids and consider paying a couple different editors for two hours of their work and compare. It’s important to judge the work rather than the fee. Consider this investment as research rather than money wasted.
When you’ve found someone who seems like a decent candidate so far, make first contact. (The contact form on the website is fine as a first step.) Introduce yourself and state what you are looking for (a developmental critique, copyediting, etc.). Give a very brief description of your project, including its genre and approximate length. Give an idea of your planned next step and any deadlines (even if only approximate ones). For example, have you already signed a contract with a subsidy press for publication next fall? Are you planning to submit the manuscript to publishers and/or literary agents after editing?
I recently contacted Ebook Launch on the advice of a fellow author, and I am extremely pleased with the results. Dane was professional and very prompt, always keeping in touch with me as the process unfolded. I had both my ebook and print versions of the cover within a week of paying for them. They were professionally done, rivaling anything I have seen from the top publishing houses. Excellent work!

2. Copyeditors aren’t the last line of defense when it comes to a book’s mistakes. Formatting, which is done after an editor has done their job, can lead to unintended errors being introduced into the text. That’s why it’s important to hire proofreaders to comb through edited text *after* the book has been formatted for print or digital. Proofreaders are your last line of defense—but they’re human too.
